Concept and use of open ceiling hammer rock drilling rig
Open-air hydraulic top hammer rock drilling rig refers to the open-air drilling equipment equipped with hydraulic rock drilling machine on the top of the drill pipe, which uses nail hammer to impact rotary rock drilling, referred to as open-air top hammer drilling rig. Open-air rock drilling rig is mainly used for drilling hard or medium hard rock. The hole diameter is generally 28-127mm, and the maximum hole diameter can reach 152mm. However, in the range of 127-152mm, open-air rock drilling rig is no longer the preferred drilling equipment. People often choose down-the-hole drilling rig first.
In the production of small and medium-sized open-pit mines, it can be used as the main perforation equipment; in the production of large-scale open-pit mines, it can also be used as drilling equipment for slope treatment, secondary crushing, and elimination of foundation auxiliary operations. Rock drilling operations and rock excavation operations are widely used in the construction of quarrying fields, railways, highways, hydropower, non-metallic mines and buildings.

Other countries open-air hydraulic top hammer rock drilling rig
The latest development of hydraulic top-hammer open-pit rock drilling rig technology in other countries is in the aspect of manipulation and control, using computer intelligent control, the rig can automatically adjust the impact pressure, drill pressure and propulsion pressure according to the changes of rock conditions such as hardness, cracks, cavities, etc., that is, the so-called rock formation induction drilling automatic control system is adopted, which avoids the jamming of drill and improves the service life and working efficiency of drilling tools, at the same time, we continue to pay attention to the working environment of the operator, safety, environmental protection and comfort.
